MACHINE non MAKING LINK MESH.

Application 'filed February 14,1924. Serial No. 692,719..

To all 'fw/7mm t may concern.'

A Be it known ythat I, Hanni? IV. SMITH, a citizen of the United States, residing` atCof niin'i'cut, in the county of Kent, YState of Rhode Island, have invented certain new and useful Improvements in Machines for Making Link Mesh; and I dohcreby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertain's to -make and use the same.

This invention relates to a m'ethod of making link mesh fabric, such las is Widely used in the manufacture of ladies handbags and other similar articles of jewelry, and also to a 'machine by which this method may be practiced. More speciiically, the invention is'directed to the provision of amethod by which mesh may be made of links having theirends soldered together and by this method such link mesh may be made ot nonsolder core ivire.

In making soldered mesh, the methods and apparatus commonly employed have in volved the use of Wire which has soldering material incorporated Within it in the torni of a core. Lengths of this Wire are bent into the form of staples, the staples inserted through links at the edge of the pieceof mesh, and then closed to form rings or links. The link orming'operation-is carried on until a piece otmesh oi' the desired length has been produced and then the piece of mesh is removed from the machine and subjected to a kheat treatment, whereupon the solder incorporated in the Wiresottens and unites so that the ends oi the linkare joined together, each link thus being an uninterrupted ring of metal.

The present invention is directed to the provision or" a method and apparatus by which such mesh may-be made of plain Wire Without solder content, and in order thatthe links ot the mesh maybe soldered together, a disc ott solder o'r` appropriate dimensions is inserted between the ends of each link as these ends are bent together to form a ring. The discs of solder are stamped or punched from a strip which is advanced step by step in coordination With the link forming tools, and these discs punched from the `hat strip are advanced by appropriate mechanism so as tolie in the path of theends of the links as those ends approach Veach tools so that la discof solder is inserted in cach link. `When a piece of this mesh of sullicient .length has been produced it is removed "from the machine and placed in a suitable furnace. Here the mesh is heated as inthe formerrprocess, so -as to cause the discs of solder` to soften and `unite the ends of thelinks so that each link in the `mesh has its ends soldered-together and is continuous. Mesh made according to this process i much stronger than ordinaryunsoldered mesh and is considerablycheaper than'soldered mesh as yheretofore made, since it is not necessary to use solder core Wire which is muchmore expensivetl'ian 'the plain Wire Which may be utilized in this process.

`While lthe principles of this invention may be `embodied inlany of the severaltypes ot machines vnow-used for makingV link mesh, such, for instance, as machines Which produce the mesh Va llink at la time, maclfiines which add a roW of links to the mesh at each operation of the tools, machines which produce mesh in the form of a flat Web or sheet, those in which the mesh moves doivnwardly or upwardly during` its production, and `machines in which the mesh is produced -in the form of a sleeve moving` in a spiral path as successive links are added to it, that form of machine which is nov7 thought most suitable for utilizing the principles above brieliy set forth is one in which the mesh is made in the form oi a iiat sheet which hangs vertically andis given a movement transversely with regard to the forming tools during the addition of successive rows and a movement in the direction of its length uponthe completion of each row sufficient to permit of the addition of the nekt successive row. In ,its general mode of operation, the machine to be described resembles the one illustrated in Patent No.

the piece of mesh.

1,078,317, issued Nov. 11, 1913, to Harry WV. and Charles G. Smith, but differs therefrom in many respects, which Will be made clear in the description to follow.

In this machine the mesh support Vis in the form of a roll having studs or pins extendingl from its surface and these pins are located so as to engage in the links of This roll is mounted on a carriage which reciprocates Withk a step by step motion with relation to the link forming tools which are mounted in a fixed location on the machine base. The tool assemblies include a device for drawing Wire from a suit-ably mounted supply, a knife which severs lengths of this Wire, a pin which moves so as to bend the severed link into the U-shaped form of a staple, a front .Ifo er which advances this staple and ints its legs through pair of links at the edge of the piece of mesh, a rear former which cooperates with the front former at the end of its advance movement and bends the staple so as to close the latter and form .i ring, and a center former which moves into the staple as the latter is being closed so as to insure that the rings so formed Will have the proper shape. The movementof the carriage With the mesh supporting pin roll is so coordinated With the action of the tools that the latter operate during the periods of rest of the carriage. Then a rouv has been completed the carriage is rotated by a step so as to position the mesh properly for the addition of another row. also at the completion of a roiv the carriage is displaced by half the diameter of a link in the direction of the axis o1' the rolly so that the staples which are to be inserted to form the rings of successive roivs will pass through a. pair of links of the row just formed. In addition to the parts labove described as forming the tool assembly, there are other devices for incorporating the disc of solder. These include means for supporting a supply of the solder material which is preferably in the form of a strip of indefinite length, a feeding means for advancing this strip as may be required, a plunger which punches a disc of the desired dimensions from the strip, and another plunger which moves this disc within the center former so that when the latter advances into its position of cooperation with the reir former the disc is in such a positien that it will be engaged by the ends of the legs of the staple .vhen the latter is bent to form the ring. The action of those parts ot the forming mechanism by which the disc of solder is cut out and properly positioned is so timed with the action of the other parts of the forming device so that a disc of solder material is inserted in each link and the actuation of the several parts of the forming device is automatic, as are also the various carriage movements. The latter moves, as has been stated, with a step-Wise motion transversely of the tools and then when a row of links has been completed the pin roll carried by the support is slightly rotated, and is shifted in the direction of its length by an amount equivalent to one half the diameter of a link, and the devices for advancing the carriage are reversed so that the carriage now travels with the same step by step movement in the reverse direction, the cycle of operations being repeated at each end of the traverse.

lt sometimes happens that due to imperfections in the Wire or the solder material, or because of a failure of the link forming tools, a link may be improperly formed or may be omitted. In order that a new link may be added at this break in the mesh the n'iachine is constructed so that it may be operated manually for the addition of these repair links, and for this purpose the carriage feed is arranged so that it may be readily reversed at any point in its travel and may then be moved forward or backward to the desired point. Also the forming tools may be driven by hand so that the repair link may be inserted and then the carriage may be moved to its previous location and the automatic production continued. There are incorporated in the machine various other features Which Will be made clear in the detailed description of the parts of which it is formed.

For a clearer understandingof the princi pies of the invention, a machine by which the method may be practiced has been illustrated in the form which is now considered preferable in the accompanying drawings, in which:

Referring new to the drawings, the main bed er table 30 of the machine is seen to be provided With standards having bearings 31 in which are journaled four shafts 32, 33, and The shaft- 32 carries fast and loose pulleys 36 and 37, the fast pulley having a handle 38 by means of which the shaft may be opera-ted by hand. The four shafts are geared together by beveled gears 59 so that they all rotate in unison. The bed 8O carries a slide 40 bolted in place. On this slide is mounted a carriage 41 which has brackets 42 for the shaft 423 of the work feeding pin roll 44. The latter may be formed as an integral portion of the shaft or else may be a sleeve Which is secured rigidly thereto. This pin roll, as is shown in Fig. 4, has pins projecting from its outer surface which are spaced so as to engage the links of the fabric being formed. Supported above and somewhat to the rear of the pin roll is a box 45 in which the completed fabric may be disposed. The finished piece of mesh coming from the pin roll is elevation of the rear usually rolled up as shown at 45 and during the operation of the machine the operator occasionally takes up the slack. Any other convenient means for supporting the completed WorkV may be used instead of the box 45.

- rThe Wire of which the linlrs are made is illustrated at 47. A supply, such as a reel, of this Wire is carried on the machine ir a convenient location and from this source of supply the Wire passes between the upper and lower plates of a friction block 48, thence passing to a feed device (Figs. 1, 5, and 12) Which consists of a slide 49 mounted in suitable Ways in a block 50. lvlounted above and cooperating With this slide 49 is a presser block 5l. The slide 49 has recesses in which are mounted coiled springs 52 against which the lower face of the presser block bears and these springs normally tend to lreep the block and slide separated. rllhe opposing faces of the presser bloclr and the slide have grooves through Which the Wire may pass and the tivo parts are held against relative lateral movement by means of the pin and slot connections illustrated so that the grooves are always in proper relative pesition. The presser has extending from its upper surface a pin 53 Which is engaged by the forked end of a lever 54 pivoted at 55 to the upper end of a rocking lever which is pivotally mounted atl 57 in an etitension from the support 50. The rear end of the lever carries a stud 58 which is acted on by cams mounted on the shaft 34, these cams being illustrated in Fig. 6. The hub 59, secured to the shaft 34, carries a cam 60 Which is designed to operate from the side of the stud 58 and so oscillate the lever 54 on its pivot 55. A leaf spring 61 holds the lever 54 with its stud against the face of the cam 60. The hub 59 also has a peripheral cam 62 which acts upon the lower end of the stud so as to oscillate the lever 54 and the rocking lever 5G about the axis of the pivot 5?. The two cams 60 and 62 are so designed that the lever is a fourWay motion, or motion through a closed path. rlhe first action is a rociin? of this lever to cause the presser to clamp the Wire in a groove between the presser and the slide. Thereafter the slide and presser are shifted laterally to feed the Wire fo- Ward. The lever 54 is then roc red about the axis of the pivot 57 so as to permit the presser to loosen the grip on the Wire and the lever with its associated parts is returned to its original position. An adj ustable stop 63, located at one sideof the lever 54, permits of regulation of the length of Wire Which Will be fed at each operation. of the feeding device.

From the feeding device the Wire is led to the device by Which it is severed, formed into staples and then these staples closed to ifao "il t) int-o which projects the end of a lever 108. This lever ispivoted in a suitable bracket atrlOQ and terminates at its other end in a roller 110 which bears against the surface of a cam 111, mounted n the shaft.

When the length or' wire has been ted through the bushing Gti into theV slot in the block 6*( the knife isactuated to sever the Wire and thereafter the bending pin forces the Wire into the grooves inthe block 78 so as to produce a staple. The bowed end of this sta )le is eventually lorced against the end oit the rontriioriner Whichvis in retracted position, The bending pin now moves down to inoperative position below the plane of the grooves in the block 7 8 and 'tuereafter the vertical slide 103 moves up CSO that the grooves 106 are in registry With the grooves in the block 78. The former non7 starts forward and pushes the sta-l ple before it through the grooves in the block T8 and into the grooves106 in the slide 103. The slide accordingly operates to provide a guide for this staple the legs ot which are now to be inserted through a pair ot adjacent links "of the mesh. The mesh 'il'abric which hangs downwardly from the sur-face of the pin roll as a tlat web or sheet will be seen, from iTig. t, to lie quite close to the face of the block 6'? and as each link is termed the carriage on which the pin roll is supported is given amovement relative to the forming tools so as to advance the sheet of mesh by an amount equivalent to the diameter. ot' a single link. Accordingly, when the front former advances the mesh will be properly positioned so that the legs of the staple will pass through a pair of links at the edge of the mesh, and the staple may now` be closed to torni a ring. In this closing there is employed a rear former which serves to bend the ends of the staple legs so as to abut cach other and complete the ring, and a center former which passes into the interior ot the ring thus formed and serves to in the bending operation.

The rear former and its associated mechanism shown in Figs. 8, 9,1e and are .mounted in a block 113, bolted to the table 'fot the machine and located face to face \vith the block 87. The for-mer, proper 114 carried on the upper end of a slide 115 which lies in a channel in the upper surface ot the block, being held there by a tace plate 116, boltedto the upper surface of the block to close this channel. This former has a recessllformed in its foruuird end and the recess has a channel 118 similar tothe channel 101 in thev front former. Also atthebottom of the recess is formed a notch 119 into which is to be introduced, Aas. will later be described, the piece of solder uiliichis to be gripped betusse 1115 eetl?? the piece, ot Wire, when the"l link is closed. This slide 115, (Fim 4) extends` through a slot in the slide 11 and carries a roller 120 at its rear end. This roller (Eig. 1) bears against the end, of an arm 121, pivoted at 122 to a block 123 mounted on the base of the machine. A caxn 1241 mounted on the shaft 32 carries va projection which strikes the side of the arm 121 and causes it to swing on its pivot and move the rear former slide forwardlthus advancing it toward the front former. It Will be seen on reference to. Figs. 21 to 27, inclusive, that as the front former moves to the rear the staple formed in the manner described will becarried to the rear and the legs ot this staple passed through the adjacent links 125 at the lower edge of the mesh. The rear former 114A moves forward to cooperate with the front former so that as the latter continues its advance the ends of the staple having passed through `these links will enter the channel 118 and there be bent inwardly so as to close the ring. However, as this action is carried on there is moved upwardly into operative position a center former 126 Which is in the form oit' a half-round bar. This center former is properly proportioned so that it may enter the recess 117 and thus serve to close the channel 118. Also the i'lat front side of this center former serves as an abutment for the adjacent links 125 during the time when the formers are moving together so as to close the link.

The center former is mounted on the upper. end of a slide 127 which is formed to enter a dove-tailed slot in the front face of the block 113. At its lower end the slide 127 terminates in a pin 128 Which rides on the upper surface of a lever 12) pivotally mounted in a bracket 130 on the lower surface of the table. The lever 129 is offset and at its rearward end extends beneath a pin 131 mounted in an aperture through the table. This pin carries a roller 132 at its upper end Which, in turn, bears against la cam 133 secured to the shaft 34. The other end of the arm 129. is held in its luppermost position against the pin 128 by a spring 1311. The slide 127, as is shown in Fig.' 1G, is provided With a. pin Which enters asuitable recess through the block 1113. At the end ot' this pin is secured a coiled spring 136 anchored at its lower end to a pin 137 Which lies in a groove extending across the lower. surface of the block 113. This spring acts to hold the slide in its lowermost position from which itis moved upwardly by the action oitA the arm 129 as described. The slide is held` in position Within the dove-tailed channel by means of blocks 13,8 which are adju'stably'l secured in place by meansoi screivs`139.

Mounted near the upper end of the slide @bleek le); Weise' at 'its upper @ed euries the center forming pin 126, and also a block (Fig. 16). This block is vertically grooved and cooperates with the upper portion of the block 146 which has a similar groove in which the pin 126 is secured by suitable screws. This block has a. passageway 141 extending through it vertically and entering this passageway is a plunger 142 which is somewhat enlarged at its lower end and is connected by means of a spring 143 to the pin 128. This spring 143 normally holds the plunger in its lower 'position. The plunger has a circumferential channel in the enlarged portion in which lie the forked ends or an arm 144 pivotally mounted at 145 in the smaller leg of an L-shaped bracket 146 which is secured to the slide 127 and has a passageway in it through which the lower end of the plunger may inve. rilhe arm 144 is rocked on its pivot by neans of a lever 147 which carries an adjustable pin 147 at its end so that the throw of the arm 144 may be regulated. This lever 147 is mounted on a stud 148 which extends from the face of the block 113. Around the shaft of this stud is a coiled spring 149 which normally tends to rock the lever so that it is clear of thearni 144. At its rear end the lever 147 bears against; the end of an arm 150 which is pivotally mounted on a suitable support 151 on the bed of the machine. The end of this arm carries a roller 152 which bears against the surface of the cam 153 on the shaft 35. The roller is held against the face of its cam by means of a leaf spring 151 attached to the support 151 and bearing against the under surface of the lever.

The upper end of the plunger 142 carries a line rod 154 which extends through a passage 154 inthe block 140, this passage lying to the rear of the pin 126. As will presently be described, the piece of solder which is to be placed between the ends of the wire of each linlr is deposited in this passageway and when the center former has moved up into position so as to assist in closing `the staple, at the proper instant the plunger 142 is raised so that the rod 154 will carry the piece of solder out and place it in the notch 119 in the bottom of the recess in the rear former, where it is held until it is gripped by the ends of the wire.

The mechanism by which the piece of solder referred to is punched from the source of supply and deposited in the passage in the hloclr 140 is as follows. Secured to the base of the block 113 adjacent the block 140, is another block 155 which carries at its upper end a guide blocl: 156 through which a strip of solder 157 passes from a sou vce of supply not shown. This strip ot solder passes over a 1roller 158 mounted on a. sind Seemed in the side wall et all @s tension 159 of the block The strip of solder then passes down in a channel 160 formed in the side face of the block 155 between that block and the block 140.

The block 155 carries a slide 161 near its lower end. This slide has an aperture near its forward end through which the strip of solder 157 passes (Fig. 17) and at its rear end a leaf spring 162, secured to the side of the block 113, forces this slide inwardly. The passageway in the slide through which the strip of solder passes is a comparatively close fit and the spring-pushed slide serves to exert a slight friction on the strip so that it will remain taut.

Mounted on a slide 163 which runs in a suitable vertical channel in the face of the block 113 is a gripping device which serves to draw the strip of solder from the source of supply. This slide, which is held in place within its channel by a spacing block 164 secured in place by adjustment screws 165, has a portion 166 which extends beyond the face of the block 163 helow the end of the bloei: 155. Through this portion is a pas` sageway 'through which the lower end of the strip 157 extends and a plunger 167 runs in a suitable passageway through the portion 166. This plunger has a T-shaped head 163 against which bear compression springs 169 The other ends of these springs enter recesses in the portion 166, Against the head 168 bears a roller 170 carried on the end of an arm 171 contacting with an adjustment screw' 173 carried in an upstanding arm 172. The arm 172 is pivotally mounted in a bracket 174 extending upwardly from the base and at its upper end the arm 172 carries a roller 175 whichbears against the face of a cam 176 mounted on the shaft 33. A. spring 177 secured at one end to the rod 171 and at the other to the bracket 174, serves to hold the roller 175 against the face of this cam. lt will be seen that as the cam 176 revolves it causes the arm 171 to reciprocate and thus reciprocates the slide 167 in the extending portion 166 of the slide 163. ln its inward movement the plunger 167 grips the strip of solder 157 and at its outward movement the strip is released. During this gripping, however, the slide 163 is moved downwardly and accordingly the strip of solder is drawn with the slide. This downward movement of the slide 163 is brought about by means oi a lever 178 (F ig. 15) pivoted at 17 9 to the face of the block 113. The forward end of this arm is forked and engages a pin 180 extending from the side of the slide 163. The latter is soclreted at its lower end and in this Ysoclret is a spring 181 which bears at its lowei'end against the bed of the machine. The rear end of the arm 178 bears against 'the end of an arin 182pivota'lly mounted on a bracket 183 extending upwardly @Qin-'the i leaf spring 184,I secured CII to this bracket, bears against the upper side of the aun and at its rear end the arn'i cairies a roller 185 which bears against thev surface o1 the cani 186 secured on the shaft 88. es the shaft rotates the arin 182 is rocked at the proper time, thus moving the slide 163 up and down. The action oi the gripping plunger 16T is properly coordinated with the n'ioveinent of this slide so that the strip of solder is gripped during the downward movement and the plunger is released when the slide is restored so that the solder inay be ei'igaged at a new point.

As the solder is drawn from the source of supply over the roll 158 discs are punched froi'n itby lnechanisni now to be described, and these kdiscs are then deposited in the passageway in the block 140 so that they may be raised by the plunger rod 154. 1t will be seen on reference to Fig. 20y that the disc 18'!- has substantially the saine crosssectional area as the wire of which the links are' niade, and the discV is preferably slightly concave on its opposed faces so that the ends of the wire may engage it and hold it tightly.

The strip led from the source of supply passes over the roll 158- down through a channel in the face ot the block 155, as has been described. At its upper end the blocl: 155 is provided with an extension 188 in which is formed a passage 189. In this passage is mounted a plunger 190 which carries at its rear end a collar 191. The plungeris engaged at a point in advance of this collar by the forked end oit a lever 192 which is carried in spaced arins 193 entei'iding upwardly iiroin the top ol' a block 19e rigidly secured to the base. rlfhe lever 192 is provided with a pin 195 to which is attached the end ol a coiled spring 196, the other end oit this spring being secured to one ot the arnis 198. rPhe rear end of the lever 192 carries a roller 19? which is engaged by a flange 198 on a cani 199 inounted on the shai't This cani is so arranged that as it rotates the iiange engages behind the roller 197 and inoves the lever 192 toward the shatt 88, thus pulling the plunger 190 outwardly in the passage 189. The lever is restored to its position of rest by the spring 19o as soon the roll is disengaged trein the cani. rlfhe plunger 190 is inoved forwardly in the pasby means of a lever 200, also inovably mounted in the spaced arins 198 and provided with a spring 201 sii'nilar in its action to the spring 196. The forward end ot the lever carries a head .202, adjustably secured in positionby its threaded niounting, and this head hears against the rear' end ot' the plunger. The rear end of thelever 200 carries a roller 203 Vwhich bears against the sur# face of a cani 20st mounted on the shaft 88. As this cani rotates it recprocates the lever `200 so as to torce the plunger 190 into the passage, and this plunger' is then positively in'oved outwardly from the base by the forked arm 192. A p

The inner end ot the' plunger 190 carries a line rod 205 which serves as a punch. This rod nieves in a sinall passageway 205 which connects with the inain passa-ge 189 and this passage is so l cated as to open into the channel in the tace of the block p 155 through which the strip oit solder 15T is drawn. The block 1110 and the block 1&0 are drilled so as to forni a recess which e3;- tends through the blocks to a point opposite the end of the channel. 208 and this bore is niounted a bushing 207 which lies in the block 1l10, and a die 208 which lies in 'the bore in the blockl 1110. This die has a. rounded portion 209 so as to fit around the iin 126 and it has a `.shallow recess 210 which lies opposite the passage through the bushing. This die which holds the bushing in place is, in turn, held in place in the block in any convenient inannor, or, it desired, may be niade integral with the block. The passage st which is formed in the blocl; M0. as has .previously been described, is located to the rear of the pin' 128 and is also in registry with the end o1 the passage through the bushing` rlhe operation ot the parts described is as Ll i t I .p l J.

iollows. lhe strip or solder drawn by the ieeding devices descriied over the roll 158 passes down in front the passage G at the time the plunger 190 withv its punch 205 is in the retracted position, but soon as a new portion of the solder has been placed. in position the lever 200 advances the plunger and forces the punch 205 through the piece of solder so that the cut-out portion 187y is advanced through the passage in the bushing into the socket 210. rlhe socket and the end oi' the punch are slightly convex sol as to indent both faces of the disc. rlhis socket is opened 'troni beneath to the passage 154. in which the rod 15st on the plunger 1&2 inoves. The plunger 190 is non7 retracted, leaving the disc of solder in the socket. During this action the forining devices have been operating and at the proper instant the slide 127 is raised so that the center former is `brought into its position ot cooperation with the rear ifornier. The plunger lil-2 also inoves upwardly relatively to the slide so that thekrod 15st will advance the disc 187v lliventually, when the two foriners are in the proper rela-tive positions, the disc is "forced into the notch 119 in the rear foriner and then as the .staple is closed the ends of the wire are forced against the disc so as to clinch it. The slide 12,7 is then lowered, carrying the eenterfornier Youtlet action, the plunger 142 being nioved relatively to the slide in this downwardlinovenient.l Thereafter the i of solderl advanced v,bythe'ii'eeiessary distance, a new disc punched out of it,

moved into position so as to be engaged by the rod st, and then the cycle of operations by which the disc is inserted in the link is repeated.

The shaft 43 on which the pin roll is mounted has previously been described as movable along` the slide d0. rlhis carriage is rcciprocated along the slide with a step by step movement, advancing` at each step by a distance equal to the diameter of a single link. To give the carriage this movenient there are provided two racks 211, 212, located side by side in passageways through a bracket 128 and a similar bracket 213 mounted rigidly on the bed of the machine. These racks are driven by similar mechanism which will be described only in connection y'ith one of them. The rack 212 has a portion extending to the right in Fig. 1, and carries at its end a forked head 214, in which is mounted a roller 215 which bears against a cam 216 on the shaft 35. As this cam 216 rotates the rack is reciprocated back and forth in a direction parallel to the airis of the pin roll. The rack is held with its roller against the face ofthe cam by means of a spring 217 connected at one end to a pin on the under side of the rack and at the other to a pin on the bracket 123. The rack 211 is similarly driven from a cam 218 on the shaft 88. On the upper surface these racks are provided with teeth which slope in opposite directions and it will be seen that as the shafts rotate both racks reciprocate, their movements away from the shaft occurring, at the same instant. One ofl these racks, however, remains inoperative during the movement of the slide in one direction, and at the end of this movement a device is automatically actuated which brings the other r ck into operation, thereby reversing the direction of travel of the carriage. v

The mechanism by which the racks are connected to the carriage consists of a housing 219, secured to the upper surface of the carriage along its rear edge. Mounted in this housing is a slide 220, shown in Fig. 7. rlhe upper' surface of the slide has two parallel channels 221 and 222 formed in it, and the outer side walls of these channels are formed .vith depressions 223 and 224. Also the bottom of each channel is apertured adjacent the depression as at 225 and 226. 1Within the housing` are dogs 22?v and 228 which are held against the upper surface of the slide by springs 229 and 239. These dogs have shoulders 281 resting on the upper surfaces of the side walls of the slide and when either dogis clear of the depression in the side wall on which it rests it will be raised so that its lower end will be clear of the aperture and in the position occupied by the dog 227Qin Fig. 3.. The position of the slide accordingly determines which of thel dogs shall be operativev to enf gage the teeth of the racks and as shown in Fig. 3, the dog 228 is in this operative position and therefore as the rack 211 is reciprocated its teeth will strike the dog` and thus move the carriage. llfhen the end .of the traverse of the carriage has been reached the slide may be moved inwardly manually by means of the handle 2252, thus reversing the action of the dogs and causing the other rack to become operative to move the carriage in its return movement. However, it is preferable that this reversing of the direction of travel of the carriage should be performed automatically and for this purpose the slide is provided with lugs 283 and 2811, near its rear end. The shaft 32 is provided with cams and 12a previously referred to, each of which cams oarrics a projection 236 on its flat surface. As the carriage is moved in one direction or the other eventually the slide will be placed so that the lugs 283, 231 will be engaged by one of these projections 236 or the other, and the rotation of the shaft will accordingly cause the slide to be moved inwardly or outwardly with the result that the action of the dogs is reversed.

At the end of the traverse of the carriage in one direction; that is, upon the comple tion of a row of mesh across the web, it is necessary that the pin roll should be rotated so that the mesh is moved longitudinally by one row so that a new row may be added at the edge of the piece of mesh. For this purpose the shaft 43 carries ratchet wheels 237 at either end. Mounted in suitable brackets 238 near either end of the bed are sliding` levers 239 which carry pawls 240 in their forward ends. These levers are held in their retracted position in the brackets by means of springs 241 attached at one end to the bracket and at the other end to the lever. rlhe rear ends of these levers are beveled, as is indicated by the dotted lines, and in their rearward position these beveled portions lie in the path of travel of studs 242, extending from the side of the cam discs 216 and 218. As the cams revolve the studs strike the beveled portions of the levers and move the levers forward and this movement accordingly takes place upon each revolution of the shafts 33 and Unde' ordinary conditions the pawls 240 perform no function but when the carriage has moved to the extreme ond of its travel one or the other of the ratchet .wheels 237 will be engaged by the appropriate pawl 2410 and the parts are so constructed that the advancing movement of the slide 289 will cause the ratchet wheel, and accordingly the shaft d3, to be rotated by a distance equivalent to the diameter of a link. The rotation takes place in the direction .which causes the. mesh to be. moved upwardly.and, thus .at the completion of a row of links the pin roll is moved so that the mesh will `be positioned properly to receive a new row. Y

As has previously been explained. the mesh fabric which is made on this machine is in the tlat form, and as each link is inserted at the edge of the mesh it is engager with two links of the row just above. Each row across the mesh contains the same number of links but the links of successive rows are necessarily offset by reason of their engagement withthe links of the preceding row, it follows that the centers of the links of one row are spaced equidistant from the centers of the links of the rows above and below. each row ofthe mesh. it is necessary that the pin roll not only be rotated by an amount i equal to the diameter of a single link, but this roll must also be shifted in the direction of its axis by an amount equal to one half the diameter of a link. This longitudinal shift is brought about as follows: Near each end of the carriage is pivoted on a stud 2&3 a lever 244. rlhe frontend of this lever bears against a rod 245 mounted slidably in an aperture in the bracket d2.' This rod has an adjustment screw 246 at its other end, the head ofwhich bears against the ratchet 237. The rear end of the rods 24e-1 are so located that they may be struck by cam lugs`2-i7 on cam discs 2118 and 124 on the shaft 32, and accordingly when the carriage is moved to one end or the other of its path of travel the rotation of the cams 248 and 124 causes the lugs to strike the end of one lever, swing it on its pivot, and thus move the rod 245. This movement of the rod 245 causes the ratchet 237 and the shaft 43 on which it is mounted to be moved axially a slight distance, the extent of which may be regulated by the proper adjustment of the screw 246. The shaft 43, as lhas previously been explained, is supported in brackets 12 but is movable lengthwise in these brackets. rlhe pin roll secured to the shaft, however, lies between brackets 2li@ which extend upwardly from a plate 250 formed with slots 251 through which extend studs 252 screwed into the upper surface of the carriage. As

the levers 2li-,4e are swung on their pivots the movement of the rod 245 caused thereby will in turn produce a movement of the shaft a3 and since the pin roll lies between the brackets 241:5) this movement of the pin roll will cause the plate 2:3() to move relatively to the carriage and this movement is permitted by the stud and slot connections above described.

It will be seen on reference to Fig. 4- that the piece of mesh 112 hangs down vertically from the face of the pin roll and its lower' edge lies near the front former block and ci 'he surface thereof. This flat sheet oil:

Consequently, at the completion ofH of mesh taut during its formation.

,mesh is s i'zretched 'taut over the pin ,roll

by reason of the pins but when it hangs clear there is a tendency for the links of the longitudinal edges of the piece to swing to i one side or theother and this would prevent the insertion of additional rings tance above the lower edge of the mesh represented by the dotted line The' vertical portions of the wire are in such position that they will lie within 'the links of alternate rows, the links beingformed around these wires by the forming tools. lhen the links are released by the forming tools they are held in the proper position by these wires and eventually as the mesh is moved upwardly by the action of the pin roll the links soV formed about the wires will slip ofi. These wires accordingly hold the sheet ln addition to the means for holding` the piece of mesh taut, just' described, it is desirable that the two links through which the legs of the staple are to be inserted should also be held against movement7 atthe time of thisinsertion. For this purpose the end of the center forming pin 126 has been given a fiat surface 256 (Fig. This surface serves as an abutment for the links 125 through which the legs of the staple are to pass. As will be seen in the ligure referred to, these links lie againstthe flat surface when the center former is in position toV cooperate with the rear" former and are thereby prevented from being displaced so that the staple would not properly engage with them.

It will be understood that the links of successive rows across the mcshlie in reverse positions of inclination.l The links naturally assume the proper position under the influence of gravity when they are released from the forming tools but sometimes a link willbe held by the links through which it is engaged and will not fall freely to the proper'position. In order, therefore, to insure that each link will incline inthe right direction there is providedy a bar 257 which is vsecured on the upper end of the slide 14() at a point near the center former 126. This bar is properly located so that as each link is released by the front and rear formers it willibe engagedby the bar and prevented from tilting in the wrong` direction. As. the slide is retracted the bar moves down with it and the link may then hang freely.

The machine here illustrated operates automatically and the parts are so coordinated. that/.the wire fed, severed, formed lll) into staples, and thesev staples inserted through the links at the edge of the piece of mesh and then closed. During this insertion of each link Vthe carriage is at rest but When the forming tools are retracted the carriage advances another step and the cycle of operations is repeated until a rev1 has been finished. Thereupon the direction of the carriage movement is reversed and the pin roll is shifted longitudinally in the carriage by the desired amount. During the formation of the link the piece of solder is cut from the strip andmeved into such position that as the staple is closed this piece of solder ivill lie between the ends of the staple so to be gripped thereby. If, through a defect in the Wire or solder, or by any failure of the mechanism, a link should be inserted in the mesh Without the solder in place, or if no link should be formed at any particular point, the operator may stop the machine and move the carriage back to the desired point and cause the forming tools to operate so as to insert the link at the proper point. The machine is capable of making mesh of various Widths, the determination of the Width of the Web depending on the point at Which the carriage feed is reversed. This can be adjusted by the proper disposition of the cams 124 and 235 on the shaft 32 and also by adjustment of the cams 248 and of the rods 245. g

While the forming assemblies and the devices by Which the disc of solder is incorporated in each link have been illustrated in connection with the machine which produces mesh in the flat form, it Will be seen that this mechanism either in its present form or with such changes in detail as might be necessary, could also be incorporated in a machine designed to produce sleeve mesh. Also the principles of this invention may be incorporated in the machine for producing mesh a roW at a time instead of a link at a time. As has previously been explained in that type of machine the Wire is previously formed into staples Which are fed to the 'forming tools which perform the function of inserting the legs of the staples through the links at the edge of the mesh and closing the staples to form links. In either case, however, the principles of operation are the same; that is, as each staple is inserted through the links a disc of solder Will be brought into proper position so that as the staple is closed its ends will grip the solder disc and maintain it in this position until the mesh is given the heat treatment.

The final step in the production of closed mesh by the method herein described is the step of closing the links by melting the solder disc gripped between the ends of each .link so as to cause this disc to soften and unite these ends. For this purpose the mesh is subjected to heat treatment in a furnace. Whenever a suflicient quantity of mesh has been produced the machine will be stopped and the piece of mesh removed from it. This mesh is then placed in a furnace which is maintained at a temperature suiiicient to melt the solder. The mesh is heated until the solder has softened to the desired extent and then the temperature is lowered so as to permit the solder to solidify. The mesh is now finished and is removed and made use of in such Ways as may be desired.

it Will be seen, therefore that the present invention provides a method for producing mesh, the rings of Which are. continuous, Without employing` Wire Which has solder incorporated in it. The mesh has an appearance which does not differ from that of mesh made of solder core Wire and it also has the strength of solder core mesh Which has been given heat treatment. lt, therefore, possesses the several advantages of this type of mesh but the materials of which it is made are considerably cheaper, While the rate of production is substantially the same.
